Collaborative product innovation network: Status review, framework, and technology solutions

The study aims to present framework and technology solutions for collaborative product innovation based on the status review. Companies are facing challenges including increasing product complexity, shorter product lifecycle, higher cost of research and development, and so on. To deal with these challenges, firms adopted practice of innovation network to co-innovate with suppliers, customers, and other external partners. However, in the past, segmental researches were mainly focused at the strategy level rather than at the project level, which provides specific guidance for product innovation. Thus, in this work, the authors propose a framework of collaborative product innovation network at the project level based on the review of innovation network. Technology solutions for collaborative product innovation network (modular product innovation network development and ontology-based knowledge integration) have also been proposed. Finally, an application in electric water heater development is also given to demonstrate the implementation and potentials of the framework.

DartWiki: A Semantic Wiki for Ontology-Based Knowledge Integration in the Biomedical Domain

Semantic Web languages and technologies can be used for the annotation, classification, and organization of knowledge assets and digital artifacts based on biomedical ontologies. In this paper, we present a semantic wiki, named DartWiki, to build ontology-based digital encyclopedia for the biomedicine domain. DartWiki provides a Web-based interface for accessing knowledge artifacts in both per-artifact and per-concept mode. In the per-artifact mode, users can access these artifacts, and annotate them in both short texts and logical statements in terms of domain ontologies. In the concept-based mode, users can navigate a graph of concepts, and review and edit the synthesized page about a selected concept, which contains meaningful information about the concept, and also its related concepts and artifacts. Smooth transitions between the two modes are achieved through semantic links. As a use case of the DartWiki, we provide an open platform for the management and maintenance of digital artifacts in Integrated Medicine. This system provides medical practitioners with relevant and trustworthy knowledge artifacts, and also means to input artifacts, to clarify their meaning, and to check and improve their quality, which encourages the inclusion and participation of users, and effectively creates an online community around knowledge sharing.

Knowledge integration and sharing for collaborative molding product design and process development

This study presents a systematic approach to developing a knowledge integration and sharing mechanism for collaborative molding product design and process development. The proposed approach includes the steps of (i) collaborative molding product design and process development process modeling, (ii) an ontology-based knowledge model establishment, (iii) knowledge integration and sharing system framework design, (iv) ontology-based knowledge integration and sharing methods development, and (v) ontology-based knowledge integration and sharing mechanism implementation. The mechanism can support collaborative molding product design and process development by providing functions of knowledge integration and sharing. Results of this study facilitate the knowledge integration and sharing of collaborative molding product design and process development to satisfy the product knowledge demands of participants, and thus increase molding product development capability, reduce molding product development cycle time and cost, and ultimately increase molding product marketability.

An ontology-based method for knowledge integration in a collaborative design environment

A collaborative design environment can be viewed as a multi-agent system where each design agent has knowledge about specific domains and can solve different problems. Several agents combine to solve a complex problem through knowledge sharing and inter operation. It is essential to construct an integrated knowledge base to improve the efficiency and consistency of complex problem-solving. An ontology-based knowledge integration framework in a collaborative design environment is presented in this paper. Ontology provides standard vocabulary, technical terminology and a domain model for knowledge integration. The representation and construction of ontology are critic problems for knowledge integration. An object-oriented concept graph representation is presented to represent ontology. It has advantages of both object-oriented methodology and Sowa’s conceptual graph. It can be translated into predicate calculus conveniently, and can represent the intension of concepts. In order to improve the efficiency of ontology construction, a semantic-based approach is presented. Firstly, a semantic affinity based clustering algorithm is presented to generate concepts from the term set of multi-agent systems. Then, ontology is constructed based on knowledge.
